4 Claims.

This; invention relates to looks andlatches and more particularly to a:lock strike zfor use on doors and similar closures.

The object of the invention is to provide a lock strike of simple andinexpensive construction especially designed for use in connection withlocks of the sliding :holt type and which may be readily adjusted bothvertically and. longitudinally to aline the keeper'andbolt without thenecessity of removing the lock strike from the door jamb.

A further objectis to provide a. lock strikecomprising an innerattaching plate and an outer strike plate adjustably mounted thereon,.said plates being provided with inter-engaging parts and havingfastening devices extending therethrough and. connected by a bar oryoke.

A further object is to provide-a lock strike including spacedclipsfitted overthe'inner ends of the fasteningdevicesand provided withlaterallips constituting guidesfior theadjacent ends of the connectingyoke, there being'coiled' springs interposed between the yoke and saidclipsso that'by moving thestrike plate against the tension of'thesprings, said strikeplate mayzbe readily adjusted toaline the keeper andslidingbolt and the parts securely held in adjusted position.

A still furtheriob ject of the invention isrgenerally to improve thisclass of devices sosas to increasetheir utility, durabilityandeificiency.

In the accompanying drawing .forming ta part of this specification andin which similar numerals ofreference indicate corresponding parts inall the figures of the drawing,

Figure 1 is acfront elevation of anadjustable lock strike constructed inaccordance with:the present invention,

Figure '2 is a verticalsectional .view 'taken on the line 2-2of Figure1,

Figure 3 is a vertical sectional zviewatakenpn theline 3-3 of Figure 2,

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure1, and

Figure 5 is a vertical sectional view illustrating a modified form ofthe invention.

The improved lock strike forming the subjectmatter of the presentinvention may be used in connection with any type of swinging closure,and by way of illustration is shown attached to the jamb 5 of a standarddoor, said jamb being provided with the usual mortise 6.

The device comprises an inner attaching plate I having a lateral tongue8 for engagement with the latch bolt of a door lock and provided with ashallow substantially rectangular seat or depression .9 formed:withlongitudinal and transverse ribs or corrugations l :and TI l.Openings are rpreferably formed inthe :plate I at the upperand:lower"ends-.thereof=for the reception of screws or-similar fasteningdevices '12, :by means of .which-theldevice may be secured in positionon :thedoor jamb. Adjustably mounted within the 1 seat ,oradepression 9r is aneouter strike Tplate l-3 having "upper and lower openings 14 andI formed therein for the reception-of the spring latch and sliding beltof the lock, respectively, said openings'beingseparated. by anintermediate web 'l6,'as shown. Theinnerface of the strike plate l33 isalso formed with horizontal and 1ongitudinal teethcorv corrugations ll,v corresponding to the teeth on the attachingplatasorthat, after thestrike ;plate is adjusted to the desired position,ithe interengagingteeth-will held said strike platelin-asetzpositlon. The seat of 'theattaching-plate J is Lformed with wall. elongated opening l-8rextendingentirelyv'through the attaching plate and icomm'unicating with saidopening l8 are verticallyialined upper and lower slots or recesses 20 to.;permit vertical adjustment oi the strike plate withereference to theattaching plate. Extendingthroughthe strike plate and attaching platearetfasteningadevices;:preferably in the form of threaded pinsonscrewsil, .the heads of which arerlooselyseated in-counter-sinksformed in=the outerzsurfaceofzthestrike plate, while theirinner ends arethreaded in the offset :ends 23 of a connecting; yoke or-bar 24, asbestshown-in Figurej2 aafithe drawing. This-baroryoke 2'4= causesthezfasteningdevices'or1pins :2I tormove in unison 'when thestrikevplate .is adjusted either verticallyprlaterally of'the-attachingplate. Loosely bearing-against the rear orinnerefaceof-the attachingplate I at the pins 2| are substantially U-shaped clips. 25, the sidewalls of whichv form guide slips I26 afor the :reception ;of the ofisetI ends 2-3 :of tthesconnecting yoke 24. Surrounding the inner :ends of:the;pins-=2l and interposed; between the clips and the offset ends ofthe connecting yoke 24 are coiled springs 21, the normal tendency ofwhich is to hold the teeth on the attaching plate and strike plate inengagement with each other.

Should the sliding bolt on the outer lock fail to register with theopening [5 in the strike plate due to sagging of the door or otherconditions, it is merely necessary to grip the connecting web 16 with apair of pliers or other suitable tool and exert a slight outward pullthereon against thetension of the springs 21 until the teeth on theattaching plate and strike plate become disengaged, when, by moving thestrike plate I3 either vertically or laterally of the door jamb, theopening IS in the strike plate may be properly alined with the slidingbolt of the door, as will be readily understood. When proper adjustmentof the strike plate has been effected, the springs 21 will automaticallyreturn the strike plate l3 to normal position and in which position theteeth will inter-engage and prevent further movement of said strikeplate.

In Figure 5 of the drawing, there is illustrated a modified form of theinvention, in which the clips 25 and springs 21 are dispensed with. Inthis form of the device, the ofiset ends 28 of the connecting yoke orbar 29 bear directly against the rear face of the attaching plate 30,while the inner ends of the screws or fastening devices 3| are threadedinto the offset ends of the connecting yoke, as shown, the constructionof the device being otherwise identical with the device shown in Figurel of the drawing. In order to adjust the lock strike shown in Figure 5of the drawing, it is merely necessary to loosen the screws 3| when thestrike plate may be adjusted both laterally and longitudinally of theattaching plate by gripping the connecting web and moving said strikeplate in the manner previously stated. After the lock plate has beenmoved to the proper position of adjustment, said lock plate can be heldin adjusted position by tightening the screws so as to clamp theconnecting bar or yoke 29 in engagement with the rear face of theattaching plate and in which position the teeth on the attaching plateand strike plate will inter-engage and prevent accidental displacementof said strike plate.

It will here be noted that in both forms of the device, the bar or yokenot only forms a direct connection between the fastening pins or screwsso as to maintain said screws in proper parallel relation duringadjustment of the strike plate when the device is in position on a doorbut also forms a handle or finger-grip, by means of which the lock platemay be conveniently adjusted to the proper position before applying thedevice to a door jamb and in addition the portion of the yoke betweenits offset ends will be located back of the attaching plate a sufiicientdistance to prevent it from constituting an obstruction which would beliable to prevent full movement of the key operated bolt of a lookthrough the opening of the attaching plate to a securing position.

It will, of course be understood that the lock strikes may be made indiiferent sizes and shapes to accommodate any style or type of doorwithout departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. A look strike comprising an inner attaching plate having its frontface provided with a seating recess formed with longitudinal andtransverse teeth, there being an opening formed in the attaching plateand vertically alined slots extending from upper and lower ends of saidopening, a yoke disposed at the rear of the attaching plate and havingits ends offset towards the attaching plate to provide ears and disposethe major portion of the yoke in rearward spaced relation to theattaching plate, said ears being formed with threaded openings, a strikeplate adjustably mounted in said seating recess and having its rear faceprovided with teeth corresponding to and adapted to engage the teeth insaid seat, the strike plate being provided with counter-sunk openings,threaded pins having heads loosely mounted in the counter-sunk openingsof the strike plate and extending through the slots of the attachingplate and provided with terminal threads engaging through the threadedopenings in the ears of the connecting yoke,
